CONSTITUTION:A piston 3 fitted about a hollow piston rod 2 at the end thereof is slidably fitted into a damper case 4 enclosing magnetic fluid therein. A hollow rod 11 projecting into the damper case 4 in inserted into a hollow portion 2a of the piston rod 2, and there is defined a clearance 12 between the rod pipe 11 and a reduced diametrical shoulder 3a of the piston 3. Magnetic circuit provided with an electromagnetic coil 13 at its part is formed among the damper case 4, the piston 3 and the rod pipe 11. Further, a check valve 16 is mounted in an oil passage 15 leading to the rod pipe 11 provided in the damper case 4.

摘要： PURPOSE:To allow a damping force to be varied by varying a magnetic field strength in a clearance between a piston portion and a rod, which clearance communicating a lower oil chamber of a damper case enclosing magnetic fluid therein with an upper oil chamber thereof, and thereby varying viscosity of the magnetic fluid. CONSTITUTION:A piston 3 having valving mechanisms 9 and 10 at an end of a hollow piston rod 2 is slidably fitted into a damper case 4 enclosing magnetic fluid therein. A rod 11 projecting into the damper case 4 is inserted into a hollow portion 2a of the piston rod 2, and there is defined a clearance 12 between the rod 11 and a reduced diametrical shoulder 3a of the piston 3. Magnetic circuit is formed among the damper case 4, the piston 3 and the rod 11, and an electromagnetic coil 13 is provided in a part of the magnetic circuit. With this arrangement, a magnetic field strength in the clearance 12 between the piston portion 3a and the rod 11 is allowed to be varied by varying electric current flowing into the electromagnetic coil 13.
摘要翻译：目的：通过改变活塞部分和杆之间的间隙中的磁场强度来改变阻尼力，该间隙将包围磁性流体的阻尼器壳体的下部油室与其上部油室连通，以及从而改变磁性流体的粘度。构成：在中空活塞杆2的端部具有阀机构9和10的活塞3可滑动地装配在其中包围磁性流体的阻尼器壳体4中。突出到减震器壳体4中的杆11插入到活塞杆2的中空部分2a中，并且在杆11和活塞3的减径直径肩部3a之间限定有间隙12.磁路形成在减震器壳体4，活塞3和杆11以及电磁线圈13设置在磁路的一部分中。通过这种布置，通过改变流入电磁线圈13的电流，允许活塞部分3a和杆11之间的间隙12中的磁场强度变化。

摘要： PURPOSE:To reduce sliding resistance and also make a unit lighter by making the diameter of the hydraulically sliding section smaller and filling only a part of an inner cylinder with hydraulic oil. CONSTITUTION:When an inner cylinder 2 moves downward against an outer cylinder 1, a piston 10 moves relatively upward against the inner cylinder 2, and the quantity of oil corresponding to the entering volume of the piston 10 in the upper chamber S21 passes through oil passages 14..., spreads out with its pressure a valve 15 against a spring 16, and flows into a lower chamber S22. This fluid resistance allows a shock absorber 1 to generate a required damping force. When the inner cylinder 2 moves upward against the outer cylinder 1, the sliding resistance of an oil seal 8 which is required to have a considerable inward tensile force working against the move of the cylinder 2, can be greatly reduced because the oil seal 18 is slidingly connected to a small diameter piston rod 6. Also, since the hydraulic oil is partially sealed in only the inner cylinder 2 the unit can be made lighter.
摘要翻译：目的：为了减少滑动阻力，并且通过使液压滑动部分的直径更小并且仅用一液压油填充内筒的一部分来使单元更轻。构成：当内筒2相对于外筒1向下移动时，活塞10相对于内筒2相对向上移动，并且与上室S21中的活塞10的进入容积对应的油量通过油路 14 ...，其压力以阀15抵靠弹簧16展开，并流入下腔室S22。该流体阻力允许减震器1产生所需的阻尼力。当内筒2相对于外筒1向上移动时，由于油封18是油封18，所以油封8的滑动阻力可以大大降低。滑动地连接到小直径活塞杆6.而且，由于液压油仅部分地被密封在内筒2中，所以该单元可以变得更轻。

摘要： PURPOSE:To enhance a sealing effect as well as reduce a sliding resistance, and thereby to lengthen life of parts, by enclosing magnetic fluid in a damper case and sealing a clearance between a piston and a rod pipe with the magnetic fluid. CONSTITUTION:A piston 3 fitted about a hollow piston rod 2 at an end thereof is slidably fitted into a damper case 4 enclosing magnetic fluid therein. A rod pipe 11 projecting into the damper case 4 is inserted into a hollow portion 2a of the piston rod 2, and there is defined a clearance 12 between the rod pipe 11 and a reduced diemetrical shoulder 3a of the piston 3.

The rod pipe 11 is provided with a pressure variable mechanism for varying pressure independence upon piston position by an orifice 11a.
